SPECIFICATION forming part of Letters Patent No. 573,803, dated December22, 1896.

Application filed November 4, 1895. Serial No. 567,869. (No model.)

To all whom, it IILCLI/ (SO/LUCI'IL.

Be it known that I, WILBUR C. AOKLEY, a citizen of the United States,residing at Adrian, in the county of Lenawec and State of Michigan, haveinvented a new and useful 'Window-Screen, of which the following is aspecification.

The invention relates to improvements in window-screens.

The object of the present invention is to provide a windowscreen whichwill be capable of ready adjustment to suit the window to which it is tobe applied and which will be adapted to be connected with the sash andto be antomatically brought into operative position when the window isopen.

A further object of the invention is to pro vide means for guiding andsupporting the screen and to enable the guides and supports to beadjusted to suit the size of the window.

Afurther object of the invention is to shield the screen from rain whenit is rolled or folded and to exclude flies when the sash is partiallyraised by preventing them from passing between the sashes.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a window provided with ascreen constructed in accordance with this invention. Fig. 2 is avertical sectional view of the same. Fig. 3 is a detail perspective viewof the supportingframe of the screen, the adjustable casing bein gremoved. Fig. 4 is asectional view of the adjustable screen-roller. Fig.5 is a detail view of a portion of the. adjustable weatherstrip. Fig. 6is a similar view of a portion of the adjustable fly-eXcluding device.Fig. 7 is an enlarged sectional view of the lower portion of the window,taken transversely of the screen. Fig. 8 is a detail sectional view online 0c 00 of Fig. 3.

Like numerals of reference designate correings.

1 designates a rectangular supportingframe designed to be mounted on awindow at the bottom thereof and constructed of suitable material,preferably sheet metal, and

comprising a bottom bracket 2, vertical guides 3, which form the sidesof the frame, and a top piece 4, which connects the upper ends of theguides. The bracket 2 is adjusted to suit the width of a window to whichthe frame is to be applied and consists of a central section 5 and endsections 6, telescoping into the central section. The vertical guides 3are provided with parallel sides or flanges to re ceive the side edgesof a window-screen 7, and they are composed of telescoping sections, onesection of each guide being provided with ways to receive the flanges ofthe othersection. The connecting top piece t is adjustable similar tothe bracket, being composed of a central section 8 and end sections 9,telescoping into the central section.

The screen is arranged upon a spring-actuated roller 10, which ismounted detachably in suitable bearings of the bottom bracket 2, thelatter being provided at its ends with upwardly-extending flanges orarms 11. The roller is adjustable and is provided with a spring-carryingsection 12 and a section 13, having a tubular portion 14, receiving thesection 12 and permitting the latter to telescope into it. In order toprevent the sections of the roller from accidentally moving inward oneach other and withdrawing the journals from the bearings of the bracket2, the roller is provided at the section 12 and at the tubular portionof the section 13 with threads formed by spiral depressions or grooves.

The screen may readily be cut the desired width to suit the window towhich it is to be applied, and its free edge, which is detachablyconnected with the lower sash of the window, is provided with asheet-metal binding-strip 15, which is folded on itself longitudinallyand which receives the screen within its folds, and this binding-stripis designed to be constructed of separate sections in order to beadjustable. The free edge of the screen may be connected with the lowersash by any suitablemeans, such as hooks and eyes or the like, and thescreen may also be applied to the top of a window and be connected withthe upper sash, if desired. a

The adjustable semicylindrical casing 16 is secured to the frame at thebottom bracket, and it is constructed of sections and is adapted to bevaried in length to suit the width of ICO the screen, and when thescreen is wound around the roller it is concealed within the casing.

hen the screen is not in use and the window is closed, it is protectedfrom rain and the like by a weather-strip l7, composed of telescopingsections and provided at its upper edge with a flange 18, which issecured to the window-sash. The bottom portion of the weather-stripextends outward from the sash at an inclination and is adapted to shedwater and to prevent the same from coming in contact with the screen.

In order to prevent flies from entering a house through the spacebetween the sashes when the lower sash is partly raised, an adjustablefly-excluding device 19 is mounted on the top of the lower sash andextends in- Ward toward the upper sash. The fly-excluding device isconstructed of sheet metal and consists of flat strips or sectionsslidingly connected and adapted to telescope to suit the width of thewindow.

The fly-excluding device extends within a short distance of the glass ofthe upper sash,

leaving a suflicient space to clear the same,

but closing the space between the sash sutfioiently to exclude flies.

It will be seen that the window-screen is simple and comparativelyinexpensive in construction, that it is adjustable and is adapted to bereadily applied to any ordinary window, and that it is protected fromthe weather.

It will also be seen that when the lower sash is partly raised flies areexcluded from the space between the sashes and are prevented fromentering a house in this manner.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificin gany advantages of the invention.

What I claim is- 1. The combination of a rectangular supporting-frame,an adjustable bottom bracket having telescoping sections and providedwith bearings, vertical guides provided with said flanges and composedof adjustable sections telescoping on each other, and a connecting toppiece composed of telescoping sections and capable of adjustment similarto the bottom bracket, an adjustable spring-actuated roller j ournaledin the said bearin gs and comprising the section 12 provided with aspirally-arranged groove, and the section 13 having a tubular portionwith an interior spiral thread engaging the said spiral groove of thesection 12 and formed by an exterior spiral depression or groove, ascreen'mounted on the roller and arranged to run in the said guides andadapted to be connected with the window-sash, substantially asdescribed.

2. The combination of a supporting-frame designed to be mounted on awindow, capable of adjustment to suit the size of the same and providedwith vertical guides, an adjustable roller journaled on thesupporting-frame at the base thereof, and com prising two telescopingsections, one of the sections being provided With an exterior spiralgroove and the other section having an interior spiral thread engagingthe groove and formed by an exterior depression or groove, and a screenarranged on the roller and adapted to run in said guides, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
